SEEDER ATTACHMENT FOR' CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 434,397, dated August 12, 1890.

Application filed March 23, 1889. Serial No. 304,454. (No model.)

To all whom it may concern:

Be it known that I, JOHNSON B. MCDANIEL, of Madison, in the county of Greenwood and State of Kansas, have invented a new and :Improved Cultivator Attachment, of which the following is a full, clear, and exact description.

My invention relates to a cultivator attachment especially designed for replanting, and adapted to be used to plant seed in missing hills of corn while cultivating for the first or second time.

The attachment is designed to be used in connection with an ycultivator having an arch.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the vlews.

Figure 1 is a partial plan view of a cultivator-arch and attached shovels, illustrating the application of my attachment. Fig. 2 is a front elevation of the same, the tongue and shovel-arms being in section. Fig. 3 is a plan View of the table and seed-box, the supports of the table being in section. Fig. 4 is a plan View of the drop-plate detached; and Fig. 5 is a side elevation of one of the handles of the cultivator, illustrating the application thereto of the drop-rod.

A cross-bar '10 is adj ustably secured between the members of the arch 11 of the cultivator by means of clamps 13 of any desired or approved construction. The cross-bar 10 consists, preferably, of an elbow-piece 14, the vertical member of which is adapted for engagement by the-clamp 13, the horizontal member being provided with a recess in its end and a set-screw 15, extending downward within the recess. The recess in the elbow piece or casting 14 is adapted to receive the extremityof the cross-bar 1O proper, which crossbar is provided with two spaced downwardlyextending socketed lugs 16, each provided with a set-screw 17.

The table 18, which is usually constructed of metal, has attached thereto and projected upwardly therefrom near each end a rod or standard 19, the upper extremities of which rods or standards are adapted to enter the recesses in the lugs 16 of the crossbar,being 22 of the seed-box, which is preferably located slightly above. the lower ends of the sides of the box, a drop-plate 2a is pivoted, the pivotal point of the drop-plate being in alignment with the central vertical axis of the box, as is also best illustrated in Fig. 3. The drop-plate is illustrated in detail in Fig. 4, and consists of an essentially triangular body a, at the reduced end of which a ring a is formed to receive a pivot-pin, and in the body a, near one corner, an opening or apertureo is produced.

The body a of the drop-plate is provided at the corner near which the aperture a' is located with an arm I), which for convenience I denominate a lever-arm. The said leverarm 1) extends beyond the side of the seedbox through an opening'formed therein, as shown in Fig. 2, and under a yoke 25, as is also illustrated in Fig. 3, the said yoke being purposed to limit the lateral movement of the drop-plate.

At one side of the opening 23 in the bottom of the seed-box a drop-aperture 26 is produced in the table, (illustrated in dotted lines, Fig. 3,) and the said drop-aperture is surrounded by a chute or tube 27, rigidly secured to the under face of the table, as best shown in Fig. 2. The drop-plate 24 is normally held so that the aperture a therein will be located between the walls of the opening 23 in the bottom of the seed-box, as illustrated in positive lines in Fig. 3. This is effected through the medium of a spring 28, attached to the plate and to the outer extremity of the lever-arm b of the drop-plate,

which spring causes the said lever-arm to contact with one side of the yoke 25, as is also illustrated in Fig. 3. To the said outer extremity of the lever-arm b of the drop-plate one end of a rod 29 is attached, which rod passes to the rear through a staple 30 or equivalent device, integral with a sleeve 31, which sleeve is adjustably secured to one handle 32 of the cultivator, usuallvby means of a set-screw 33, as illustrated in Figs. 1 and 5, the said handles being, as is usual, secured to the shovel-arms of the cultivator.

It will be readily observed that by drawing upon the rod 29, which for convenience I denominate a drop-rod, the drop-plate will be drawn to the rear and the seed in the opening therein will be conveyed to the outlet or drop-aperture 26 in the table, from whence the seed will fall from the tube or chute 27 to the hill to be planted. As soon as the drop-rod is released the spring 28 acts to draw forward the drop-plate to its normal position to receive the seed for another hill.

The attachment is designed especially to be used in replanting missing hills of corn while cultivating for the first or second time, as before stated.

In operation the handle of the right-hand shovel-arm is held loosely by the operator, and when the missing hill is nearly under the spout or tube 27 the operator suddenly draws the drop-rod 29 rearward, whereupon the seed is dropped, as heretofore stated, and the shovels, following after, eltectually cover the seed.

It is obvious that the attachment may be expeditiously and readily applied to any cultivator having an arch.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A replanting attachment for arched cultivators, consisting of a cross-bar capable of attachment to the arch of the cultivator, a table suspended from the cross-bar having a drop-opening and a chute attached beneath said opening, a seed-box located upon the updrop-opening and a chute attached beneath said opening, a seed-box located upon the upper face of the table, provided with an opening in its bottom, an apertured drop-plate pivoted upon the table beneath the seed-box, provided with an outwardly-extendingleverarm, a yoke spanning the said lever-arm, and a drop-rod attached to the extremity of the levenarm and extending rearward over the handle of the cultivator, substantially as shown and described.

3. The combination, with the arch of a cultivator, of a cross-bar, clamps adjustably scouring said cross-bar to the arch, a tablesuspended from said cross-bar, provided with a drop-opening and a chute surrounding said opening, a seed-box located upon the upper face of the table, provided with an apertured bottom, a spring-actuated and apertured dropplate pivoted upon the table beneath the seedbox, and a drop-rod attached to the said dropplate capable of sliding upon one handle of the cultivator, substantially as shown and described.

4E. The combination, with the arch of a cul' tivator, a cross-bar, and clamps adj ustably securing said crossbar to the said arch, of a table suspended from the cross-bar,provided with a drop-aperture and a chute surrounding said aperture, a seed-box secured upon the upper face of the table having an opening in its bottom, a drop-plate pivoted upon the table beneath the seed-box, provided with an aperture near one end, and a lever-arm projecting outward beyond said seed-box, a spring attached to the table and to the leverarm, a sleeve capable of adjustment upon the handle of the cultivator, and a rod attached at one end to the lever-arm of the drop-plate and capable of sliding in the said sleeve, substantially as shown and described.

5. In a cultivator attachment, the combination, with a table provided with a drop-aperture and a seed-box supported upon the said table and having an opening in its bottom, of an essentially triangular drop-plate pivoted upon the table beneath the seed-box, provided with an aperture near one end and a lever-arm, a spring secured to the table and the said lever-arm, and a drop-rod attached to the lever-arm of the dropplate and extending rearwardly over the handle of the cultivator, substantially as shown and described.
